Make sure you either use a fresh, name brand battery or correct AC adapter.

Turn all controls down at first as it is possible this pedal may feedback internally if controls are all up.

I have a peavy classic 100 2x12 1975 has a high pitch squeal coming out of amp when powered on

If this happens only when the guitar is plugged in, most likely there are two possibilities. The first, you have some issues with the electronics in the guitar OR are using an acoustic guitar witch has an extremely sensitive pickup that provides nothing but feedback. If this is happening with the guitar unplugged, there is a mountain of possibilities.

Hi I have a pair of Mackie SRM450s. When applying power I get a high pitch squeal whether I have speaker leads connected or not. After flicking the low cut or contour buttons on and off it then goes away....

Make sure you have ALL interconnected parts of the system powered from the SAME receptacle or power conditioning module. This MAY require you running an extension cord back from where your speakers plug in to supply power to the mixer. The ground bounce in power wiring in building can cause feedback or even destroying the sensitive input circuits of your system. As an electrical engineer I see these problems frequently. I think they should include this information with sound equipment user manuals, but they don't and people have trouble and damage their equipment. Doing this MAY also fix the problem you are having.

BR-1180 freezing & high-pitch ring

Check your power supply to the unit. Low voltage COULD cause this.

Also make sure a setting is not "looping" the audio back into itself.

High pitched noise from amp

Theonly user serviceable thing for you to check is the batteries OR power supply. If that were low, that could cause the problem.

Lexicon alpha interface is recording a faint high pitched sound

Check for ground loops.

You MIGHT be able to cut the noise by setting the EQ's to clip the highs.
